网购灯箱在脱影照相中的应用研究

脱影照相的方法通常是使用专用灯箱,然而这种拍摄方法不仅对配光要求高,而且专用灯箱价格昂贵,不便携带。为了改进现有的拍摄方法,改善拍摄效果,脱影照相不妨使用网购灯箱。实验证实:改进后的网购灯箱,在拍摄效果、用光方法、抗外界光线干扰、色温平衡和价格方面,均优于专用灯箱。由此可见,利用互联网有助于我们寻找和发现更加适合刑事技术工作需要的产品,这对提升证据能力,提高办案效率和质量,有效打击刑事犯罪具有重要的现实意义。

Application Research of Online-purchased and Self-modified Light Boxes in Shadow-free Photography

Shadow-free Photography is normally supported by dedicated light boxes, which has obvious draw-backs that the light distribution should reach the top and the dedicated light boxes are very expensive and not porta-ble. To improve the existing photography method, purchasing ordinary light boxes through Internet is feasible. In fact, it has been proved that cheap self-modified ordinary light boxes are better than dedicated ones, because of their effective photography outcome, the lighting method, the capacity for anti-interference and the balance of color temperature. Therefore, the internet can supply us with more suitable devices for the forensic science, which would improve the evidence credibility, the efficiency and quality of case-handling and the effect of crimes fighting.
